HENRY R. ELLSWORTH, OF BOSTON, MASSACHUSETTS.

SMOKE-CONSUMER.

SPECIFICATION forming part of Letters Patent No. 739,659, dated September 22, 1903.

Application filed October 6,1902.

To all whom it may concern:

Be it known that I, HENRY R. ELLs WORTH, a citizen of the United States, residing at Boston, in the county of Sufiolk and State of Massachusetts,have invented certain new and useful Improvements in Smoke-Consumers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to devices for consunning the smoke of boiler-furnaces without permitting it to pass into the chimney; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure l is a perspective View of a boiler provided with a smoke-consumer according to this invention. Fig. 2 is a partial longitudinalv section through the boiler. Fig. 3 is a section through the reservoir D, drawn to a larger scale.

- A is a boiler of any approved construction.

B is the boiler-furnace, and G is a hot-air space inside the boiler between its waterspaces. The space 0 is usually filled with the heated products of combustion.

In order to prevent the formation of smoke by the boiler-furnace,-a reservoir D is pro: vided and is preferably arranged on topof' the boiler, so that it may be heated. This reservoir is supplied with any volatile chemical substances which will assist combustion, such as hydrocarbons. The reservoir D is provided with perforations d for the entrance of air, andE is an outlet-pipe, which is connected to the reservoir D and extends to the boiler-furnace. The pipe E has outlet-openings e onits upper side inside the reservoir D. The pipe E is arranged in the reservoir below the perforations of its upper part or top, and

its openings e are arranged above the level of the volatile liquid in the reservoir. The pipe E is provided with a coil F, which is arranged within the hot-air space 0 of the boiler.

G is a steam-jet pipe, which is connected to the upper end of the coil F where it enters Serial No. 126,098. (No model.)

. the boiler and which operates to cause acurrent of air and steam to pass through the said coil to the boiler-furnace, the air being drawn through the reservoir D and bringing with it some of the volatile substance with which the said reservoir is supplied.

H represents distributing pipes 'or jets which are connected to the lower part of the pipe E and which project within the boilerfurnaceover the fire on its grate.

Whenever smoke is being formed in the boiler-furnace, steam is admitted through the pipe G by a valve g and causes the carbon of the smoke to be consumed within the boilerfurnace, so that no smoke issues from the boiler-chimney.

What I claim is- 1. The combination, with a boiler-furnace, of a reservoir for a volatile substance which will assist combustion, having air-openings at its top, a pipe connected to the said reservoir above the level of the liquid in the said reservoir and discharging into the said furnace, and a steam-jet pipe which draws air through the said reservoir and forces it into the said furnace, connected to the aforesaid pipe between the reservoir and the furnace, substantiallyas set forth.

2-. The combination, with a boiler, of a reservoir for a volatile substance which will assist combustion arranged on top of the said boiler, and having air-openings at its top, a pipe connected to the said reservoir above the level of theliquid contained in it and discharging into the boiler-furnace and provided with a coil which projects within the hot-air space of the said boiler, and a steam-jet pipe connected to the inlet end of the said coil and operating'to draw air through the said reservoir and force it through the said coil and into the boiler-furnace, substantially as set forth.

3'. The combination, with a. boiler, and its furnace; of a reservoir for a volatile substance which will assist combustion arranged above the said boiler and provided with a at a. point above the level of the liquid conit enters the said hot-air space, substantially tained in it, a series of distributing-pipes H as set forth. 1o 7 connected to the other end of the pipe E and In testimony whereof I affix my signature projecting within the said furnace, a pipein presence of two witnesses.
